[Nerve sheath myxoma. A case involving the maxillary sinus].
A myxoma of nerve sheaths involving the maxillary sinus was observed in a 12 year-old boy. The tumour, necrotic and calcified in this central area, was detected by a radiological opacity. In this periphery, the histological features were characteristic, showing lobules surrounded by fibrous tissue. In these lobules, spindle-shaped or stellate tumour cells were scattered in an abundant "myxomatous" matrix. The child is in good health fifteen months after surgical treatment. The histogenesis of this rare tumor is discussed in relation to this case and to those cases previously reported in the literature.
